Abstract :
This paper is in the scope of fuel cell robust control. As a matter of fact, reliability and lifetime are the two major key points for fuel cell commercialization, especially as far as proton exchange membrane technology is concerned. To bring about these essential properties, the system designer needs to build a robust control law based on a suitable and on-line state of health knowledge. For this latter diagnosis purpose, we describe a new on-line impedance spectroscopy which gets accurate data while still allowing load monitoring.
